Cross-platforms operating systems are:
· UNIX
· LINUX
UNIX is a multitasking operating system. Some versions of UNIX have a command line interface but most versions of UNIX offer a graphical user interface.
Linux is a popular, free, UNIX-like graphical user interface operating system. It is an open source software. Linux provides a great deal of liberty to those that interact with Linux technology. Although Linux runs on many kinds of equipment, it is best known for its support of IBM-Intel PC-based hardware.
